News content:
The Central Meteorological Station issued four weather warnings on February 19, alerting the entire middle and eastern regions of China to an impending severe cold wave, heavy fog, strong wind, and sandstorm. It is expected that from February 19 to 22, most regions in the middle and eastern parts of China will experience a sharp drop in temperatures, with an average or minimum daily temperature decrease of 8 to 12 degrees Celsius.
The areas likely to be affected include the middle and eastern parts of Northeast China, southern parts of North China, the Huanghuai, Jianghuai, and Jianghan regions. The sudden arrival of the cold wave will bring significant discomfort to local residents, especially the elderly, children, and those with weakened immune systems, who will need to pay special attention to keeping warm.
Meanwhile, heavy fog, strong wind, and sandstorms may also have a negative impact on transportation, aviation, agriculture, and other industries. Heavy fog can reduce visibility and affect traffic safety; strong wind can lead to tree falls and damage to power facilities; sandstorms can cause air pollution and affect public health.
In response to this severe weather, the Central Meteorological Station advises meteorological departments at all levels to strengthen monitoring and early warning, release weather information in a timely manner, and ensure the safety of the public. At the same time, local governments should also take measures to ensure normal living conditions, focusing on winter heating, traffic safety, and environmental protection.
